President Barack Obama's first campaign manager, David Plouffe, said Sunday that GOP presidential nominee Donald Trump is a "psychopath," adding that he thinks Hillary Clinton will face an easy road to the White House in November.

"I mean, basically, we have a psychopath running for president. I mean, he meets the clinical definition, okay," Plouffe told Chuck Todd on NBC's "Meet the Press" Sunday.

Plouffe backed up his diagnosis by listing off psychopathic symptoms that he said Trump has displayed: "The grandiose notion of self-worth, pathological lying, lack of empathy and remorse."

Still, Plouffe conceded: "I don't have a degree in psychology."

Plouffe, who helped lead Obama to victory in 2008, said he believes Trump's campaign strategies — or seemingly lack there of — are going to lose him the race.

"I think the assessment was that Donald Trump would try and do some things to appeal to the middle of the electorate, to appeal to suburban college-educated women," Plouffe said. "He's not."
